Mean: the mean is the average fo the data series for example: 2 4 7 9 4 2 46 5 you would add them together and divide by the number of 9.625 Cluster: A cluster is a small group or bunch of something Outliers: Outliers are observations that are distant from the rest data. Trends: Trends is a statistical technique to aid interpretation of data. Dot Plot: A Dot Plot is a graph that shows dots instead of columns Tally Chart: A Tally chart is a chart that you use to record data before putting it on a graph. Pictographs: Are graphs that show pictures instead of bars or columns
Bar Graphs : There are four types of bar graphs. Histogram, column, vertical and double bar graphs. Histograms: A histogram Is a type of bar graph that shows continuous data. Strip Graph : a strip graph shows proportions or percentages as part of a strip Pie Graph : A pie graph shows percentages of the data in a circular graph. Steam and leaf graph A steam and leaf graph has a stem and the numbers that come off the stem are called the leaves Scatterplot : is a graph that shows data that is placed on a co-ordinate table Box and Whisker graphs: are used to find the median and upper and lower quartiles. Line Graph: is used to show measurements like height and weight Mean : Is used to show the average number in a series of data Median: Is the number in the middle in an ordered series of data Mode: Is the most occurring number in a series of data Range: Is the difference between the highest and lowest numbers Inter quartile range: It is the middle 50%(25 to 75%) of a series of data. Implications: the conclusion that can be drawn from something, although it is not explicitly stated. Variables: are things that change suddenly and unpredictably. Sample :a small group of data Surveying: Surveys are used to gather a group of data . Patterns in data: groups of data that are in a pattern. Relationships in data: is a connection between the data. Frequency table : shows the frequency of data in a group. Conclusions: the end statement in an investigation Generalisations: a principle, a theory etc. with general applications
